What is Glaucoma?
Glaucoma is a disease of the optic nerve and is the leading cause of irreversible blindness worldwide. This condition is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to loss of central vision and blindness. Glaucoma is usually, but not always, associated with elevated pressure in the eye (intraocular pressure). Generally, it is this elevated eye pressure that leads to damage of the eye (optic) nerve. In some cases, glaucoma may occur in the presence of normal eye pressure. This form of glaucoma is called “normal tension glaucoma” (NTG) and is usually associated with poor regulation of blood flow to the optic nerve. Continue reading Are You Showing Signs of Glaucoma?
